Can't scroll the content of JEditorPane in JScrollPane

JDK1.2FCS-N:

I can't scroll the content(html file) of JEditorPane in JScrollPane and followings are printed out.
To reproduce:
java TextViewPane t-basic0.html

Exception occurred during event dispatching:
java.lang.NullPointerException:

a:575)
